Powerpath : performance and check I/O loadbalance
Hi gurus
I have a question on Powerpath. I know it does load balacing, as well as path failover. In our environment we have 4 paths specifically to a LUN and we are told that if one path goes down, the performance of the DB or whatever it is using that LUN, wont be affected because the other 3 paths will take care of the IO for that LUN. The only thing that would be decreasing is redundant paths to that LUN.
Is this correct? How can we be sure that the performance of a database/application running on that LUN (which has one dead path) is the same as before? Is there a way to check/monitor how the I/O is loadbalance between the paths, with Powerpath?
Appreciate your replies! If this has already been explained in other threads, kindly let me know so I can have a look at those too.
